According to at least one example embodiment of the present invention, provided is a face authentication system including: a criterion setting unit that sets a criterion of face authentication performed on a user so as to be different in accordance with a state of an access target system accessed by the user; and a face authentication unit that performs face authentication of the user based on the criterion.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A biometrics authentication system comprising: at least one memory configured to store instructions; at least one processor configured to execute the instructions to: set a biometrics authentication performed on a user to a first threshold having a first similarity degree between biometric information of the user and a target when the system is in a first operation state, wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user to the system; set the biometrics authentication performed on the user to a second threshold having a second similarity degree between biometric information of the user and the target when the system is in a second operation state, the second similarity degree being lower than the first similarity degree; and perform biometrics authentication of the user based on the first or second threshold.
2. The biometrics authentication system according to claim 1 , wherein the state of accepting the biometrics authentication result is at logoff from the system of the user.
3. The biometrics authentication system according to claim 1 , wherein the first operation state is a state of instructing the user to take a test and the second operation state is a state of instructing the user to perform learning.
4. The biometrics authentication system according to claim 1 , wherein biometrics authentication of the user is performed based on a similarity degree between a biometrics image of the user and a comparison target image.
5. The biometrics authentication system according to claim 1 , wherein the processor is configured to notify the user of a result of biometrics authentication of the user.
6. The biometrics authentication system according to claim 5 , wherein the processor is configured to perform any of a first notification indicating that recognition of a face image is successful and face authentication is allowed, a second notification indicating that recognition of a face image is successful and face authentication is not allowed, and a third notification indicating that recognition of a face image is failed in accordance with a result of face authentication.
7. The biometrics authentication system according to claim 1 , wherein the processor is configured to output a biometrics image of the user when a predetermined condition regarding a result of biometrics authentication is satisfied.
8. The biometrics authentication system according to claim 7 , wherein the predetermined condition is that biometrics authentication has not been allowed continuously for predetermined times.
9. The biometrics authentication system according to claim 7 , wherein the predetermined condition is that biometrics authentication has not been allowed for predetermined times within a predetermined period.
10. The biometrics authentication system according to claim 1 , wherein the processor is configured to use a biometrics image acquired when the user logs in the system for the first time as a comparison target in biometrics authentication at second and subsequent login.
11. The biometrics authentication system according claim 1 , wherein at least one of the first or second threshold is determined based on at least one of position information on a terminal on which the user operates, network connection related information, and a start time interval of a content received from the system.
12. The biometrics authentication system according to claim 11 , wherein biometrics authentication of the user is performed based on a similarity degree between a biometrics image of the user and a comparison target image, and wherein, based on at least one of position information of a terminal on which the user operates, network connection related information, and a start time interval of a content received from the system, a similarity degree used as at least one of the first or second threshold of biometrics authentication when it is determined that a playback environment of the content has changed is higher than a similarity degree used as a threshold of biometrics authentication when it is determined that a playback environment of the content has not changed.
13. A biometrics authentication method comprising: setting a biometrics authentication performed on a user to a first threshold having a first similarity degree between biometric information of the user and a target when the method is being performed in a first operation state, wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user; set the biometrics authentication performed on the user to a second threshold having a second similarity degree between biometric information of the user and the target when the method is being performed in a second operation state, the second similarity degree being lower than the first similarity degree; and performing biometrics authentication of the user based on the first or second threshold.
14. A non-transitory storage medium in which a program is stored, the program causing a computer to execute: setting a biometrics authentication performed on a user to a first threshold having a first similarity degree between biometric information of the user and a target when the program is executing in a first operation state, wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user; setting the biometrics authentication performed on the user to a second threshold having a second similarity degree between biometric information of the user and the target when the program is executing in a second operation state, the second similarity degree being lower than the first similarity degree; and performing biometrics authentication of the user based on the first or second threshold.
15. A biometrics authentication system comprising: at least one memory configured to store instructions; at least one processor configured to execute the instructions to: set a biometrics authentication performed on a user to a first type of biometric authentication having a first similarity degree between biometric information of the user and a target when the system is in a first operation state, wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user to the system; set the biometrics authentication to a second type of biometric authentication different from the first type when the system is in a second operation state, the second type having a second similarity degree between biometric information of the user and the target lower than the first similarity degree; and perform biometrics authentication of the user by using the first or second type of biometrics authentication.
16. A biometrics authentication system comprising: at least one memory configured to store instructions, a first threshold having first similarity degree between biometric information of the user and a target, and a second threshold having a second similarity degree between biometric information of the user and the target; and at least one processor configured to execute the instructions to: set a biometrics authentication performed on a user to the first threshold having the first similarity degree when the system is in a first operation state, wherein the first operation state is a state of accepting a biometrics authentication result used for determining login permission of the user to the system; set the biometrics authentication performed on the user to the second threshold having the second similarity degree when the system is in a second operation state, wherein the second similarity degree is lower than the first similarity degree; and perform biometrics authentication of the user based on the first or second threshold.
